CT (carbon steel)

Scope of use: accumulation and storage of cold liquids (water, ethylene glycol, propylene glycol and alcohol solutions) as well as heating system liquids. The standard operating range of the tank is between -10 and +95 °C. A design is optionally available for temperatures down to -40 degrees.

Product material: carbon steel.

The tank is designed to accumulate cold liquids from various sources, as well as to build cold supply systems. Its distinctive feature is large sized flange connections (DN 50 to DN 300) (threaded connection pipes are optionally available). The S-TANK CT series tank improves the cooling system flexibility and acts as a hydraulic separator of the system circuits. It provides an excellent combination of the following cold sources:

  • Chiller
  • Thermal pump (in cold supply mode)
  • Industrial centralized refrigeration plants
  • Geo-collector
  • Solid fuel boiler

Can be used with any heat source:

Gas-fired boiler

Solid fuel boiler

Electric boiler

Thermal pump

The presence of such a tank in the cold supply system extends the service life of the refrigeration equipment compressor units by increasing the system pulsing and reducing the number of compressor power up and down. When it comes to a solid fuel boiler, such a storage tank protects the boiler against accidental boiling and subsequent explosion, increases boiler efficiency, reduces fuel consumption by 50%, and prevents the chimney from becoming actively clogged with tar.

Depending on the intended use, the tank can be insulated with the following materials:

  • The outside of the tank is covered with a 20 mm thick black rubber foam. The inside of the tank is unpainted according to the requirements for tanks operating as part of heating/cooling systems.
  • If the tank is operated as part of a heating system, the tank insulation may be performed using NOFIRE technology with 70 mm thick, 100% recyclable polyester (which is an environmentally friendly material) with a high R-value and B-s2d0 high fire-resistance class in accordance with the European EN 13501 requirements.

At the customer’s request, the tank is available in the following versions:

  • fully made of carbon steel + tank insulation
  • fully made of AISI 304 stainless steel + insulation (the tank in this case is marked CT-SS).
  • with any configuration of pipe fittings and flanges on the tank
  • with various insulation thicknesses at the customer’s request
  • with various tank diameters and heights
  • with additional heat exchangers
